.TH fmt_ulong 3
.SH NAME
fmt_ulong \- write an ASCII representation of an unsigned long integer
.SH SYNTAX
.B #include <libowfat/fmt.h>

size_t \fBfmt_ulong\fP(char *\fIdest\fR,unsigned long \fIsource\fR);
.SH DESCRIPTION
fmt_ulong writes an ASCII representation ('0' to '9', base 10) of
\fIsource\fR to \fIdest\fR and returns the number of bytes written.

fmt_ulong does not append \\0.

If \fIdest\fR equals FMT_LEN (i.e. is zero), fmt_ulong returns the
number of bytes it would have written.

For convenience, fmt.h defines the integer FMT_ULONG to be big enough to
contain every possible fmt_ulong output plus \\0.
